使用Spring Reactive Data自动配置连接到AWS Keyspace

我正在尝试使用spring-boot-starter-data-cassandra-reactive连接到我的AWS密钥空间，但收到以下错误：

Error creating bean with name 'cassandraSession' defined in class path resource [com/pams/framework/windsoncore/configurations/CassandraConfiguration.class]: Invocation of init method failed; nested exception is com.datastax.oss.driver.api.core.AllNodesFailedException: Could not reach any contact point, make sure you've provided valid addresses (showing first 1 nodes, use getAllErrors() for more): Node(endPoint=cassandra.us-east-2.amazonaws.com:9142, hostId=null, hashCode=33a6c4f3): [com.datastax.oss.driver.api.core.DriverTimeoutException: [s5|control|id: 0xe0ebe047, L:/10.0.0.128:54474 - R:cassandra.us-east-2.amazonaws.com/3.12.23.155:9142] Protocol initialization request, step 1 (OPTIONS): timed out after 500 ms]

我尝试了他们的文档，很管用，但我想使用Spring自动配置和反应式Cassandra Repos。我在appation.yml中添加了所有配置，并将trustStore信息作为JVM参数传递。但我无法忘记这些错误。我试着四处寻找这个问题，但没有找到有效的解决方案。

如果有人能帮我一下，我将不胜感激。

我还尝试了以下方法：

@Configuration
@Slf4j
@EnableReactiveCassandraRepositories
public class CassandraConfiguration extends AbstractReactiveCassandraConfiguration {

  
  @Override
  protected String getContactPoints() {
    return "cassandra.us-east-2.amazonaws.com";
  }

  @Override
  protected int getPort() {
    return 9142;
  }

  @Override
  protected String getKeyspaceName() {
    return "windson";
  }

  @Override
  protected CqlSession getRequiredSession() {
    // TODO Auto-generated method stub
    DriverConfigLoader loader = DriverConfigLoader.fromClasspath("application.conf");

    return CqlSession.builder().withConfigLoader(loader).build();
  }
}

---

解决方案

您需要将application.conf文件中的连接超时时间增加到：

datastax-java-driver {
  advanced.connection {
    connect-timeout = 5 seconds
    init-query-timeout = 5 seconds
  }
}

或升级到Java驱动程序4.9，其中init-query-timeout已从500毫秒增加到5秒。
